Abstract
The utility model provides a pressed hollow rubber ring mould, which is characterized in that a processing hole is arranged on the middle section, an annulus upper mould with a concave groove concaved upwards is arranged inside of the mould, and a processing hole is arranged in the middle of the upper mould; an annulus lower mould with a concave groove concaved downwards is arranged inside of the mould, which is combined by a plurality of the related pin holes and the location pins inside the holes on the mould wall, a hole to install a gas nozzle and communicated with the concave groove inside the mould is arranged on the mould outer wall. The long strip or annulus hollow blank positioned in the upper and lower mould concave groove circular, through inflating and pressurizing on the blank air core, and heating pressing sulfur forming around the blank, is compressed one time to be a hollow rubber seal ring with equal wall thickness, sized, non shrinkage in the inner cycle, the utility model overcomes fundamentally the shortcoming that the hollow rubber ring has no good sealing effect because of a joint, shrinkage inner cycle, uneven wall thickness, irregular shape of the ring in the prior art, the mould has the advantages of simple structure, conveniently operation, safety and reliability, and a long service life.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of mould of suppressing the hollow rubber circle.
Background technology
The hollow rubber circle is widely used in the industrial production as seal.The traditional fabrication method of hollow rubber circle is to place a mandrel in the middle of the strip blank, piecemeal after the compacting, mandrel is extracted out and is surrounded circle, bonds with strength adhesive at link, makes it to form annular ring.The maximum deficiency of this method is that needed round rubber circle is not the circular whole of a standard, and bending back cylindrical is subjected to stretch and easily causes wall unevenness, and interior circle easily produces the ripple gauffer by compression, thereby influences sealing effectiveness.Therefore, be necessary fully prior art is improved.
Summary of the invention
For overcoming the prior art above shortcomings, the utility model provides a kind of wall thickness and regular hollow rubber ring mould of shape such as can once be pressed into.
The utility model is realized by following technical proposal: a kind of mould of suppressing the hollow rubber circle, it is characterized in that its middle part is provided with fabrication hole, inside is provided with the ring-type patrix to the groove of fovea superior, and its middle part is provided with fabrication hole, inside is provided with the ring-type counterdie to recessed groove, combine by pin-and-hole corresponding on its die wall and the alignment pin in the hole, and the hole of the installation valve that is communicated with the mould inner groovy in the outer wall setting of mould.
The inwall of close groove is provided with its cylindrical and wears mould in the ring-type of tooth bar in described patrix or the counterdie, by the setting of mould in this, makes the round tooth bar reinforcement that upward forms in the hollow rubber circle that suppresses.
Section configuration after the groove combination in the described upper and lower mould is circular or oval, to satisfy the different requirements of using section.
The utility model compared with prior art has following advantage and effect: adopt such scheme, can be with on being positioned over, strip or ring-shaped hollow blank in the counterdie groove, process is to the hollow plenum of blank, to the peripheral hot-press vulcanization moulding of blank, make it wall thickness such as once being pressed into, regular, the non-wrinkle hollow rubber seal of interior circle, fundamentally overcome existing hollow rubber because of joint is arranged, interior circle wrinkle, wall unevenness, shape irregularity and the sealing effectiveness that brings be not good to be waited not enoughly, and this mould structure is simple, and is easy to operate, safe and reliable, long service life.
